GAS BURNER.

Y Application filed December 3, 1921. Serial No. 519,580.

My invention relates to limprovements in gas burners, and more particularly has reference to gas burners adapted for use in heating appliances of the radiantl type, although they are adaptable in many forms of apparatus where high temperature liames are desired. The burner has many advantages including the minimizing of possibility of back ring. It is efficient, noiseless, durable, simply and economically manufactured, and conveniently applied.

Referring to the accompanying drawings, Fig. l is a plan view of a suitable form of coarse grid burner for burning natural gas. Fig. 2 is a longitudinal section on the line 2-2 of Fig. l. Fig. 3 is an end view looking down upon Fig. l. Fig. 4 is a plan view of a similar form of burner with a fine grid suitable for burning artificial gas. Fig. 5 is a view looking from right to left thereat. Fig. 6 is a plan View looking down upon the lower portion of Fig. 4, the upper portion being broken away, and the grid being removed. Fig. 7 is a plan 'view illustrating a modified structure for securing the grid. Fig. 8 is a view looking from right to left at Fig. 7. y

7 is the shank or supply tube of the burner, and 8 the elbow portion of the burner which is preferably made of brass. The mouth of the burner is preferablyy substantially rectangular as shown and is provided with a grid such as 9-10 which is preferably made of cast iron with slots such as l1 through which the gasescapes. The corners of the gas grid may be beveled as indicated at 17 so that after the same has been introduced between the jaws 12-13 of the burner, said jaws may be bent rover the beveled corners to hold the grid securely in place as shown in Fig. 7.

I prefer to make the grid of cast iron of sufficient body to enable it to absorb and radiate the heat while at the same time reducing liability to corrosion. `While the slots are shown cutv straight, other formev may be employed, and a central web or spine 1G is preferably provided. This also provides additional strength and facilitates cut-- ting large groups of grids simultaneously.

In the modification illustrated in Fig. 8, opposite sides of the grid are beve-led and the jaws 12-13 are extended inwardly to conform to the bevel as shown, or the sides may be tapered as illustrated in Fig. 5, and the innerv walls of the jaws may be formed accordingly. In the modifications shown in Figs. l and 2, a sulficient margin or solid portion is shown at opposite ends of the grid allowing for the passage of rivets such as 18 for securing the grid between the jaws. The proportions and arrangements otherwise are preferably substantially as shown.

Of course it will be understood that various modicat-ions may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

I claim:

In a burner of the class described, a rectangular base portion having an opening, a grid in said opening having a substantially central longitudinal web and laterally projecting prongs from each side thereof forming slots between said prongs for the escape of gas, said opening having projecting anges at the longitudinal sides thereof between which said grid may be secured, and means at the ends of said grid and the ends of said opening for securing said grid in position, said grid being beveled and said projecting flanges extending inwardly to engage said bevel.

In testimony whereof I hereunto aliiX my signature.

WALTER KENNEDY.
